6. Macular Hole MH

The macula is the centre of the retina (the nerve tissue lining the back of the eye). A macular hole occurs when there is a full-thickness defect of the macula. Usually this just develops due to aging. It is also more common in short-sighted (myopic) people and can occasionally occur after trauma. Patients will notice blurring of their central vision and/or distortion (where straight lines appear crooked). It is painless. Most macular holes will require surgery to close the hole.
